AUTOMATIC LEVELING CARRIAGE FRAME.

Application led May 7,

`This invention relates to' carriages and vehicles and has special 'reference to an automatic leveling carriage frame particularly adapted for use with a side hill harvester 'andother like implements.

More especially the device is designed to be used for the purpose of. carrying an automatic McCormick Deering harvesteror any other machine to which it maybe applied,

the principal object ofthe invention being to maintain such harvester at all times in perfect level alignment while in operation on uneven or hill side land.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully 1described, illustrated in the accompanying drawings and specitiby t-he bearings 20. Thus no matter how the cally claimed.l n

In t-he accompanying dra-wings like characters of reference indicate like parts in the several views, and: I

Figure 1 is a plan View of the device with ndicated by simple platforms.

Figure 2 is a sideelevation hereof.

Figure 3 is an'enlarged plan View of a certain gimbal frame used in connection herewith. Y

Figure 14 is a sidev elevation thereof.

Figure 5 is an end view thereof.

In the embodiment of the invention herein disclosed there is shown a wheeled frame having a rear axle and a front axle l1 which are connected by suitable hounds 12. These axles carry the rear wheels 13 and front wheels 14, the front wheels const-ituting steering wheels but the steering mechanism being omittedas forming no part of the present invention. from the rear axle and rearwardly from the front axle are pins 15 which lie in the samev vertical plane, the rear pin 15 naturally being somewhat higher than the front pin 15.

At 16 is a rectangular frame having end members which are parallel to the axles 10 and 11 and on each o'f these end members is carried a stirrup consisting of an endless length of rod metal of general diamond shape and bent to provide parallel center portions 17 which lie beneath the respective end members of the frame 16, the remainder of the stirrup being bent up vertically to Projecting forwardly 1927. serial No. 1s9,6e4.

provide inwardly inclined sides 18 terminating at their upper ends in semi-circular portions `19 which engage over the respective pin 15. The rear stirrup is of course slightly longer than kthe front stirrup so that the frame 16y hangs horizontally from t-liese pins 15.

frame or platform 22 at its central portion. Since the arrangement is such that the On each side member of the frame 16l there is provided a bearing 20 for the recep-` tion of pins 21 projecting from the harvester )center of gravity of the swinging support f is below the center of suspension the wheel frame maytilt laterally without disturbing the level position laterally of either the harvester frame 22 or .the'frame 16. Also the wheel frame may tilt lon itudinally without disturbing the level'position of the harvester frame or platform 22 since this is supported` wheel frame is tilted-by the unevenness of the ground the harvester will at all times remain level.

In order to bring the pins 15 in axial in or carried by such bolster or holsters. Y

Under these circumstances the front and rear stirrups will be of equal lengths.

There has thus been provided a simple.

and eicient device of the ykindvdescribed and for the purpose specified.

It is obvious that minor.l changes'may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, Vdesired` to confine the invention to the exact form herein yshown and described, but it is desired to include all such as properly come within the scope claimed. y

' Having thus described the invention, what is claimed as new, is:

1. In a device ofthe kinddescribed, a wheeled frame, a ysupplemental frame suspended therefrom `for free rocking move-` ment on axes extending longitudinally fof' said wheeled frame, and a harvester. frame suspended from the supplemental frame for rocking movement on an axis transverse thev supplemental frame.

. 2. In a device of the kind, described, a,

aXles, pivot pins projecting from said axles side members, and a harvester frame having n toward each other stirrups hung from said aligned pivot pins engaged in said bearings. pivot pins, a supplemental frame having In testimony whereof We affix our signa- 10 front and rear members parallel to said axles tures.

and supported in said stirrups, said supplemental frame also having longitudinal side WILLIAM O. TURNIDGE. members, aligned bearings supported by said f ARCHIBALD L. TU RNIDGE.
